Abstract: This invention relates to an operation valve device for supplying a pressure oil to an actuator such as a hydraulic cylinder and a hydraulic motor. This operation valve device includes first and second oil ports (3, 4) for causing the pressure oil supplied to an input port (2) communicating with a pump (P) to flow out selectively into pressure chambers (B1, B2) on both sides of an actuator (B) through outlet ports (6, 7), first and second communication ports (12, 13) bored concentrically and facing each other in such a manner as to allow the first and second oil ports to communicate with a tank port (10), first and second valve ports (14, 15) bored concentrically and continuously outside the first and second communication ports, respectively, a pair of support shafts (16, 16) inserted into each of these valve ports in such a manner as to face each other, vacuum prevention valves (9, 9) fitted to the tip of these support shafts so as to open and close the communication ports, respectively, and check valves (8, 8) fitted into the intermediate portion of the support shafts in the axial direction so as to prevent the outflow of the pressure oil from the first and second oil ports to the input port side, respectively. Since the vacuum prevention valves (9, 9) and the check valves are disposed on the concentric support shafts, the operation valve device of the present invention is compact in size and can reduce oil leakage.

Abstract: Infrared light barriers or video control systems are used, as is known, in monitoring bounded, plane areas, for example a level crossing. However, both solutions have the disadvantage that they are unreliable or are of a very complicated design. The invention provides a video control system which permits reliable evaluation using simple means. For this purpose, a camera is used to take and store two fields in each case, one being taken without flash, and the other with. A differential image, now containing only signal components caused by the light of the flash is obtained from the two fields. Given the presence of a three-dimensional object in the monitored area, there is produced on the side of the object averted from the flash a shadow signal which is evaluated and, if necessary, fed to the alarm-triggering device. <IMAGE>

Abstract: The present invention relates to a drive for machines winding cables or similar elongate objects on and off a drum, i.e., machines of the so-called portal type, comprising at least two columns (1,2). Each of said columns supports a support elements (3,4) that can be moved in the vertical direction of said columns by a power unit. Each of said support elements carries a bearing boss (5, 6) intended for insertion into the centre hole of a cable drum (7) or the like. The bearing bosses (5, 6) can be moved in approximately the vertical direction with the aid of a second power unit for the purpose of raising the cable drum (7) from the foundation with clearance. At their upper ends the support elements (3,4) are suitably connected by a transverse, telescopically extensible crossbeam (8,9), such that the support elements (3,4) and the cross beam (8,9) can be moved vertically as one unit. The cable drum (7) can be rotated for the purpose of winding cable on or off by means of least one somewhat resilient wheel (11) which can be rotated by at least one drive (10). The wheel (11) can rest against the flange (12,13) of the cable drum (7) so as to drive it. The wheel (11) is supported in a bearing at one end (14) of a link (15), which is secured approximately at its centre by a pivot to one of the support elements (8,9) and at its other end (17) it is secured to one end of a guy (18) whose other end is pivoted suitably to one of the column (1,2) so as to be stationary. The length of both the link (15) and the guy (18) is so selected that when the bearing bosses (5,6) have entered the centre hole of the cable drum (7) but the drum has not yet raised by them, the drive wheel (11) should be at a defined but small distance from the flanges (12,13) of the drum (7) such that the drum flange (12,13) is pressed against the yielding wheel (11) in a defined manner when the drum (7) is raised by the bearing bosses (5,6) by a predetermined amount.

Abstract: An improved electro-optic modulator (21) for a light valve device of the kind wherein the modulator (21) is sandwiched between cross polarizer elements (22, 23). The modulator (21) includes a ferrroelectric ceramic panel having a plurality of parallel grooves (G) forming intervening parallel walled ridge portions (R). A series of address and reference electrode pairs are formed on the ridge side walls with each electrode pair being substantially parallel and opposingly centered on a normal across the intervening ridge portion. The electrode pairs of the series are staggered in location along respective ridge portions to define an array having a linear direction at about 45° to the direction of the panel grooves. The panel can be oriented between the polarizer elements with the polarization directions of the elements parallel to and perpendicular to the linear direction of the array.

Abstract: A method and apparatus for delivering supercritical fluids uses one or two high pressure vessels. Each vessel is cooled below the critical temperature of the fluid while the vessel is being filled. The inlet is then closed and the vessel is heated to attain a predetermined pressure. The outlet of the vessel is then opened and supercritical fluid flows from the vessel for use in various processes such as extraction or chromatography. As the fluid flows from the high pressure vessel, the pressure is controlled by adjusting the temperature of the high pressure vessel. Usually, the temperature of the vessel will be increased as the supercritical fluid exits from the vessel. When two high pressure vessels are used, the vessels can be refilled on an alternating basis so that a continuous supply of supercritical fluid can be made available as long as it is required. The high pressure vessels can be two pieces of stainless steel tubing. The system is essentially maintenance free as there are virtually no moving parts. With previous delivery systems for high pressure fluids, high pressure pumps are used. These pumps are relatively expensive and can be subject to problems such as noise and leakage.

Abstract: What is disclosed is a method of encapsulating hydrocarbon systems with the combination of an emulsifier solution and a reactive silicate solution. The method comprises the addition of an emulsifier solution to a hydrocarbon, for example, crude oil, then adding the reactive silicate solution to the emulsifier solution and hydrocarbon mix. Upon adding the reactive silicate solution the mix changes to a thick gel consisting of agglomerates of microspheres having typical diameters of 2 to 4 micrometres and less. The agglomerates are only loosely bound and the microspheres are easily dispersable into individual entities. Upon drying the wet gel yields a free-flowing powder. The encapsulation does not chemically alter or degrade the oil in any way.

Preferred heterocyclic nitrogen compounds are azoles such as benzotriazoles and alkyl-substituted benzotriazoles. Preferred amino-substituted interpolymers comprise amino-substituted ethylene propylene norbornene terpolymers. The polymers of this invention are oil soluble and are useful as dispersants, viscosity index improver dispersants, and as antiwear and antioxidant additives in oleaginous compositions.

The elastically collapsible valve (6) is mounted on the stent as the commissural points (5) of the valve (6) is secured to the projecting apices (4). The valve prosthesis (9) can be compressed around the balloon means (13) of the balloon catheter (11) and be inserted in a channel, for instance in the aorta (10). When the valve prosthesis is placed correctly the balloon means (13) is inflated thereby expanding the stent and wedging it against the wall of aorta. The balloon means is provided with beads (14) to ensure a steady fastening of the valve prosthesis on the balloon means during insertion and expansion. The valve prosthesis (9) and the balloon catheter (11) make it possible to insert a cardiac valve prosthesis without a surgical operation comprising opening the thoracic cavity.
